MPC5777C :What is the underlying technology behind IPS, is it NXP proprietary?

Marc_Haddad — Tue, 11 Mar 2025 15:56:44 GMT

1) "IPS" when referring to the peripheral bus,is it acronym for "IP Sky Blue"? What is the underlying technology behind this bus, is it NXP proprietary?

2) "Intelligent bus bridging gasket", referred to in the Platform Configuration Module section "12.1 PCM memory map and register description" of the reference manual. Is this another name for the Peripheral Bridge/AIPS?

Thx

Marc

Hi Marc,

1) For IPS, it does refer to "IP Sky blue". Here's an AppNote AN3952 of MPC56xP AN3952, Qorivva MPC560xP and MPC564xL Compatibility - Application Notes (nxp.com)

that has a section to explain what the AIPS is. The A in AIPS stands for AHB bus which is an ARM IP, and then IPS is an NXP proprietary that's historically named Sky Blue (due to the diagram line being drawn in blue color)

2)The block diagram of the device shows that the PCM peripheral is connected via Bridge B, which the bridge is AIPS_0. So, the "Intelligent bus bridging gasket" should just refer to the AIPS bus/bridge.
